I have some of those lights sitting on shelf with other less than useful products we have evaluated.
Beware these Motorcycle Headlight Conversion Motorcycle LED Headlamps Super Bright Lighting-Gold - USD $ 43.99
and these Marsing CREE XM-L U2 24W 1500lm Waterproof 3-Mode 6500K White Light Motorcycle LED Bulb (12-60V) - USD $ 18.74
While they look great in the ads, the beam is too narrow to be of any use on a motorcycle. The beam is very "laser pen" like. They come in a box marked "Transformers."
Also be aware that not all LED elements have equal output for the power consumed. Right now the American company CREE has the highest output per watt by far. Epistar of Taiwan is in second place at about 80 to 90% of the CREE output per watt. The generic Chinese elements run about 1/2 the output of the better lights. And most importantly, zillions of Chinese LEDs are sold claiming to have CREE elements that actually contain copies of copies of copies of the Chinese elements.
Also, while many lights you see look the same, there are Chinese companies that sell housing molds to the other Chinese companies, who in turn make identical looking light housings. These companies put their choice of circuitry, wiring, heat sink compound, and LED elements in the housings. And,...sadly... a very high percentage claim to have CREE elements that use the generic Chinese elements.
I know this paints a scary picture for the consumer, but on the bright side, some VERY expensive lights are repackaged with off the shelf wiring harnesses and off the shelf lights from some of these manufacturers. Yes, Dhose lights.
The mark up is horrendous. Every time I see someone post pics of Dhose lights I cringe at the money wasted and the ability of advertising to get insane profit levels out of the consumer.
Getting back to the cheap Chinese lights, the cheapest 10 watt broad beam (flood) lights do serve well to be seen by others. Based on reports by others, the failure rate appears to be slightly more than 1 out of 4 within a year. If it lasts a year it's probably good for many years. That's not too bad considering the cost.
We have evaluated many lights and do offer high quality CREE LED light kits with off the shelf wiring harnesses remarkably similar
to other much more expensive light kits.
